[U-Boot] [PATCH 0/3] Introduce TPM driver model and STMicroelectronics ST33ZP24 TPMs

[Christophe Ricard]

Hi,

This patch serie introduce TPM driver model allowing to instantiate a TPM
using U_BOOT_DEVICE macro for platform_data or device tree.

As an information, there is no TCG transport protocol official specification
for i2c for TPM1.2. The TPM uclass allows to support different kind of bus
(LPC, I2C, SPI) keeping the TPM command duration in common.

Also, this serie introduce TPM1.2 from STMicroelectronics ST33ZP24 with
I2C and SPI support. It has been ported from existing Linux drivers.

This has been tested on Beagleboard xM.

Best Regards
Christophe
